How to use Dental Sealants to Fight Cavities

Posted on March 13th, 2025

Fuquay-Varina dentist, Dr. McCormick at Fuquay Family Dentistry, discusses how dental sealants can help you fight cavities.When kids get cavities, it can be a real bummer. Tooth decay can cause pain, missed school, or even more serious issues. According to the PEW Charitable Trusts, in 2008 children went to hospital emergency rooms over 215,000 times for preventable dental issues. Those visits cost more than 100 million dollars.  Tooth decay, if left untreated can cause tooth loss, and infection, and can hinder a child’s speech development. Lost or infected teeth can also prevent children from eating nutritious food. One of the greatest tools available to parents and kids to help prevent decay is dental sealants. Fuquay Family Dentistry is here to explain what dental sealants are and how they can help prevent tooth decay in kids. 

The Process of Tooth Decay

First, it’s important to understand how the process of tooth decay works. Everyone has something called a biofilm on their teeth. It sounds complicated but think of it as all kinds of bacteria woven together to form a thin blanket on the teeth. Biofilms aren’t inherently bad. We need healthy bacteria in our mouths to help keep the oral environment working properly.  Problems occur when we do things to cause the good bacteria to die off. When this happens, the bad bacteria start to overgrow and cause damage to our teeth, called cavities.

Researchers have mixed opinions on the best way to treat biofilms on the microbial level, but for someone trying to prevent cavities daily, you can start by practicing good oral hygiene, eating healthy meals, limiting snacking or consuming sugary foods and drinks, and visiting the dentist regularly. You should also consider dental sealants. 

Dental sealants: a cavity-preventing superpower 

You may have heard the term before, but what is a dental sealant? A dental sealant is a thin layer of plastic or other dental material that is painted on the chewing surface of the molars. It serves as a barrier, so decay-causing bacteria cannot access the tooth surface. Children without sealants are three times more likely to have cavities in their molars than kids who don’t. Additionally, dental sealants cost 1/3 the cost of a filling. While nothing can replace brushing and flossing, sealants are a powerful protective factor. 

Who can benefit from sealants?

Dental sealants are most effective when applied to the permanent molars of children as soon as they come in. But anyone can have sealants placed.  Ask Fuquay Family Dentistry if now is a good time for sealants for you or your family. 

How much do they cost?

The application of the thin layer of plastic to the chewing surface of the molars ranges from $30-$60 per tooth. But most dental insurance plans cover some of the cost or check and see if the in-house membership plan covers some of the costs. Long-term, sealants will save you money. 

What is the procedure like?

Since there are bacteria on the tooth surface, Fuquay Family Dentistry will thoroughly clean and dry the tooth before applying the sealant. Once the tooth is prepared, he/she will apply a gel that buffs the surface. The gel will be removed, and the plastic material will be painted on. Fuquay Family Dentistry will use a special light to make the layer harden and cure the tooth.

How to care for dental sealants

Once the sealant is applied you simply brush and floss normally. The layer will remain intact and prevent any bad bacteria from penetrating the tooth surface. Continue your regular dental visits as well to keep an eye on things. The sealants should last for several years. If, and when Fuquay Family Dentistry notices they are losing effectiveness, he/she will discuss reapplication. 

Dental sealants to the rescue 

Dental sealants are an effective way to prevent cavities in children. The American Dental Association reports dental sealants reduce the risk of decay by 80% in children. Sealants are a fraction of the price of fillings and can protect anything else. If you are interested in learning more about dental sealants, call Fuquay Family Dentistry today!
